Aeria does have games we have asked and received new English voice-overs for. DKOnline springs to mind as the most recent title. Whether we do or not is dependent on a number of things, generally how much/how prevalent, how important to game and of course the cost/time factor.

Whether Scarlet Blade will be or not will depend on the above and is not decided by me.

in otherwords as long as it does not affect the server we don't care if u use korean voice paks right =P lol j/k

Well, all I can say is that if Aeria chooses to have English voices for this game, I really hope they have voice actors who can play up the game's personality. XD

As long as they can all sound "sexy" (minus the Sentinel voices, you'd need someone that can do a very good child's voice), without sounding creepy at the same time, I'd be very happy. But they do need a homosexual male for this guy right here:

I honestly wouldn't mind keeping the korean voices, so long as there's dialogue or subtitles to accompany.
Especially after seeing one or two MMOs dubbed, I'm not quite sure it'll be for the best(at least see about a dub option in the options menu)

You can google "Queen's Blade NPC" and find a video(by Kraken973) that has all the NPCs in it, to see what kind of voice actors they'd have to find
